A screen member 25 pivoted tothe As shown in Figure 1, the feeder in which the casing 1 to swing about the axis 26 encases the beater drums of the present invention are inlower kicker 24 and a pair of endless conveyors tended for use, comprises a casing 1 having an 2'7 and 28 for conveying hulls and trash away inlet 2 at the upper part thereof and an outlet 3 from the machine.-

The present invention is not concerned with the structural details of the general assembly illustrated in Figure 1, those details being described and claimed in my said pending application, Serial No. 634,223. ticularly concerned with the construction of the polygonal cleaner and beater drums or kickers adapted for use particularly with the saw cylinders of gin feeding apparatus. The cleaner drums 6, 8, 13 and 15 are illustrated and describedin my aforesaid pending application. The beater" Each of the cleaner: drums 6, 8, 13 and 1 5 are identical in construction. It is therefore necessary to describe. only one. of .them to disclose the inventive concept embodied therein. For thispurpose the. cleaner drum 6. is selected and is illustrated in Figures2aand- '7." The drum 6 comprises a shaft'29. adapted to be rotatably mounted in. journals. (not shown) suitably formed on opposite end walls of thecasi'ng l of the gin feeder. Polygonal end walls and31 are suitably se-- cured in spaced relation to the shaft 29. Each of 9 these end Walls, comprises a hub 32 and a flange 33. by means .of which sheet metal plates which form the surface of thebeater-drum maybe fixedly secured: to the shaft-29 As shown in Figure '7, the end wall i0 is shapedas aregular pentagon, but the invention is not restricted to any particular. number of sides. It is preferable, however; that in crosssection, the drum have asection of that .of a. regular polygon. This is obviously I necessaryin order to secure proper-balancingof the drum on the shaft 29; 1 1

As shown in Figure 7, the walls of the pentagonal drum 6 are formed by five similar sheet metal plates 34-, 35, 36, 3'7 and 38 bent to fit over thecorners of the flanges on the end walls 30 and 3.1. These sheet metal plates are suitably secured, as by rivets 39 to the flanges of the end walls 30and 31. In orderto secure the sheet metal plates. to each other, the outer edges of each plate v are turned up to formflanges 40 adapted to beriveted together so as to stiffen the whole beater drum assembl-ylengthwise. The outer edges of the flanges 40 are equidistant from the axis of the shaft 29, as are the corners 41 of each of; the

sheets 34', 3'5, 36,-"emana- 38.. By this construe: tion, the corners 41 also serve to knock hulls and trash from theseed cotton in substantially the same manner as the fianges m formed on theedges of the sheet metal plates. q

It will be evident from consideration of Figures ll 2 and 7 thatthe flanges 40 form a 'very strongreinforcement for the sheet metal plates whichconstitute the periphery of the cleaner drums. It will also'be evident. that the angular formation of the sheet. metal' makes a, very. strong joint. at.

or other drums of the prior art in which spikes projecting from the drum surfaces are used to knock off the hulls from the seed cotton during its passage through the cleaner.

Exactly the same principle of construction is involved in the manufacture of the beater drums lland 22 shown in Figures 5 and 3 of the drawings respectively. In all of these drums, there are as many sheet metal sections as the polygon has sides. For example, in the pentagonal drums, shown in Figures 5 and '7, there are flve similar sections. In the square drum shown in Figure 3, there are four similar sections, each of which is bent to fit the correspondingly shaped end walls,

, each of which has flanges at its opposite edges bent up. to be secured to and contact with similar flanges on the adjacent sections.

'- In the heater or kicker drums 11 and 22, howevjer, one of the flanges of each section is made longer than the other. For example, in the square" kicker drum shown in Figure 3', the section 42 has a flange ,43 formed at one edge thereofland a wider flange 44 formed at the other edge. The'edge 43. of the flange 43.is at the same. distance from the center of the kicker shaft 45. as. is the corner 46. of the plate 42'. The wider flange 44 is serrated. along its edge 44" so as: to provideteeth 4'1 which extend into the spaces 48 between. the saws 49 to knock off any hulls which might be carried in the. spaces 48 formed by the blocks 50. spacing the saws 49 from each.

other.

The pentagonal kicker drum 11, shown in- Figures 5. and 6, isconstructed on the same principle as that shown in Figures 3 and 4. Theonly difference is that called for by the differences of the polygon. angles. between adjacent sides of the drum sections. For example, the plates 46. are bent so that the adjacent sides, are arranged; at

an angle of 90 to each other, while the plates 51 of the pentagonal kicker, shown in Figure. 5,. must be bent. at an angle of. 108 to each other. Each plate. 51, is: provided at: its opposite edge with a narrow flange 52 and a serrated wide flange 53, the wide flange 53: being serrated to provide teeth, 54 to enter the spaces'55 between the saws 56 for the purpose of knocking off hulls which, would otherwise be carried. around by the saws along with the cleaned cotton. As

shown in Figures 3, 4, 5, and 6, the serrations of; the wider; flanges 4,4 and 53 have their bottoms substantially; flush with the edges of: the narrower flanges 43 and 52,, respectively.

,Itis thought that the invention. and numerous of its attendant advantages will be understood.

fromthe; foregoing descriptionand it is obvious that numerous changesmay be, made .intheform, construction and arrangement of the several parts without departing from the spirit-or scope of invention, or sacrificing any of its attendant advantages; the form herein'described.

being a preferred embodiment for the purpose ofillustrating my invention.
